ISO 22514-2:2017描述了一种确定统计数据的程序,用于估计产品和过程特征的质量能力或性能。这些质量特征的过程结果可分为八种可能的分布类型。统计测度的计算公式被放置在每个分布中。
本文件中描述的统计方法仅与连续质量特征相关。它们适用于任何工业或经济部门的工艺。
注:该方法通常适用于大量连续过程结果的情况,但也可用于小系列(少量过程结果)。
ISO 22514-2:2017 describes a procedure for the determination of statistics for estimating the quality capability or performance of product and process characteristics. The process results of these quality characteristics are categorized into eight possible distribution types. Calculation formulae for the statistical measures are placed with every distribution.
The statistical methods described in this document only relate to continuous quality characteristics. They are applicable to processes in any industrial or economical sector.
NOTE This method is usually applied in case of a great number of serial process results, but it can also be used for small series (a small number of process results).
